Aha! Eureka! I think I may have stumbled across something interesting.......
LEE, Robert (1793-1877)- The Last Days of Alexander, and the First Days of Nicholas, Emperors of Russia (London, 1854)
Here is the online link:
https://archive.org/details/lastdaysalexand01leegoogpages 26 discusses house at "Yoursoff"......,page 31, discusses what his plans are when he "decomissions himself"....
somewhere in the book is a section on Tsar Alexander 1st admonishing someone about a pregnant woman being mistreated.....hmmm
Hmm....is the name "Yoursoff" linked to the name "Usov"
.....is there a connection there
.....its pretty out there I agree...but....I wonder if somehow this is the connection of the rare dna we carry....the time period is correct from what I have been informed about how far back we share a common ancestor....and yes I am aware of the research being carried out on the various family lines....interesting times we live in......!
